First record of the pan-tropical Yellow Water Pea Vigna luteola (Fabaceae) seed from a NW European shore.
The first record of a seed of the Yellow Water Pea Vigna luteola (Jacq.) Benth. stranded in Northwest Europe was collected along with other trans-Atlantic disseminules from a south-west facing beach in County Kerry, Ireland (v.c.H1) during March 2022.Minchin, Dan ; Hill, Rosemary ; Lewis, Gwilym

Abstract
A Collective Effort to Update the Legume Checklist.
Taxonomic names are critical to the communication of biodiversity—they link data together whether it be distribution data, traits or phylogeny. Large taxonomic groups, such as many plant families, are globally distributed as is the taxonomic expertise of the family. A growing knowledge base requires collaboration to develop an up-to-date checklist...Le Roux, Marianne ; Döring, Markus ; Bruneau, Anne ; Miller, Joe ; Govaerts, Rafaël …

954. DELONIX REGIA
Delonix regia (Bojer ex Hook.) Raf. (Leguminosae), a red‐flowered, bird‐pollinated, showy tree, endemic to Madagascar, is described and illustrated for the second time in Curtis's Botanical Magazine, since it first featured in 1829.Lewis, Gwilym

Evolutionary convergence or homology? Comparative cytogenomics of Caesalpinia group species (Leguminosae) reveals diversification in the pericentromeric heterochromatic composition
The Caesalpinia Group includes 225 species and 27 monophyletic genera of which four occur in Northeastern Brazil: Erythrostemon (1 sp.), Cenostigma (7 spp.), Libidibia (1 sp.), and Paubrasilia (1 sp.). The last three genera are placed in different clades in the Caesalpinia Group phylogeny, and yet they are characterized by... -

Resolving nomenclatural ambiguity in South American Tephrosia (Leguminosae, Papilionoideae, Millettieae), including the description of a new species
Taxonomic studies of Tephrosia Pers. (Leguminosae, Papilionoideae, Millettieae) in South America have highlighted the need to resolve some nomenclatural issues. Five new synonyms are proposed and a new species is described. Nine lectotypes of accepted names and synonyms, and one neotype, are here designated. An identification key to the taxa...de Queiroz, R.

Two new species of Poecilanthe (Leguminosae: Papilionoideae: Brongniartieae) from Bolivia and Brazil
Two new legume species, Poecilanthe goiasana G.P.Lewis from Brazil and Poecilanthe boliviana G.P.Lewis from Bolivia, are described and illustrated. Previously seven species of the genus were recorded from Brazil, and one from Bolivia. A summary is given of the current circumscription of the papilionoid legume tribe Brongniartieae Hutch., to which...Lewis, Gwilym ; Tebbs, M. ; Wood, J. R. I.

Phylogeny and divergence time estimation of Chamaecrista ser. Rigidulae (Leguminosae: Caesalpinioideae)
Chamaecrista is a monophyletic genus, but most of its infrageneric categories have been shown to be paraphyletic, including series Rigidulae which currently comprises 30 species, all endemic to Brazil and most occurring in the cerrado vegetation of the central highlands of the country. This molecular phylogenetic study tests the monophyly...de Souza Alessandro, Oliveira ; Lewis, Gwilym ; Telles, Mariana ; da Silva, Marcos

Do tropical plants have smaller genomes? Correlation between genome size and climatic variables in the Caesalpinia Group (Caesalpinioideae, Leguminosae)
While a number of studies have suggested that temperate plants typically have larger genome sizes (GS) than tropical ones, recent analyses have not convincingly confirmed this. We have selected the widely distributed Caesalpinia Group (Leguminosae) to test this hypothesis. We used flow cytometry to estimate the amount of DNA in...Souza, Gustavo ; Costa, Lucas ; Guignard, Maïté ; Van-Lume, Brena ; Pellicer, Jaume …

Characteristics of the exine and aperture of pollen grains of Eriosema and Rhynchosia (Leguminosae – Papilionoideae – Phaseoleae)
The genera Eriosema and Rhynchosia, which comprise approximately 150 and 230 species, respectively, belong to the tribe Phaseoleae and to the subtribe Cajaninae. The pollen morphology of 49 species of Eriosema and 13 of Rhynchosia were studied using scanning electron microscopy to identify diagnostic characteristics that could aid in the...Oliveira, Ana ; De Borges, Ricardo ; Perez, Ana ; Lewis, Gwilym ; Silva, Juliana

Taxonomic Synopsis of Eriosema (Leguminosae: Papilionoideae, Phaseoleae) in Brazil
Eriosema is a pantropical genus occurring mostly in savanna vegetation and grasslands of tropical environments, with approximately 150 species and two centers of diversity, one in Africa with about 110 species, and the other in the Neotropics with about 40 species. Considering the large number of Eriosema taxa in Brazil,...Cândido, , Elisa ; de Vargas, Wanderleia ; Bezerra, Luísa ; Mansano, Vidal ; Vatanparast, Mohammad …
